Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25900, here are decompositions:
- 11 + 25889 = 25900
- 53 + 25847 = 25900
- 59 + 25841 = 25900
- 101 + 25799 = 25900
- 107 + 25793 = 25900
- 137 + 25763 = 25900
- 167 + 25733 = 25900
- 197 + 25703 = 25900
Showing the first eight; more decompositions exist.
